' Claims.. 5(c1. 'zei-ps4) This invention lrelates lto .an umbrellaattache ment `for Inozzlesand has las .its primary,=obj,ect theprovision of a water shedding appliance :for the fuel delivery nozzlesof liquid fuel dispensing pumps or tanks, such as are employed in fuel`supply stations,irrdelivering fuel to the reservoirs of motorVehiclesfas `a means for preventing vthe flow of -waterinto :thereservoir around l' the vnozzle where the filling operation is effectedin the open during a rain.

Another object is to provide -an -umbrella attachment-for fueldeliverynozzles which maybe easily and quickly applied toyanozzleandremoved ltherefrom and which Vis so formedasl-to effect shedding i ofwater -which may bedeposited on the upper portion-of the nozzle,as'lby'rain, orwhich-may shedo'nto the nozzle from the hose to which thenozzle is attached, to prevent the Water from entering the intake of areservoir into which the dischargey end of the nozzle is inserted.

Another object is to provide an umbrella attachment of the abovecharacter which may be formed in one piece, as by molding of rubber, orrubber composition, and which is so formed as to effect a grippingengagement with the nozzle to which it is applied without the aid ofextraneous fastenings.

` Another object is to provide a construction in the umbrella attachmentwhereby while affording a water shedding cover for the fuel intake of areservoir will permit the escape from the reservoir of air displaced bythe volume of liquid being delivered to the reservoir.

With the foregoing objects in view together with such other objects andadvantages as may subsequently appear the invention is carried intoeffect as hereinafter described and claimed, and illus-V trated by wayof example in the accompanying drawing, in which:

Fig. 1 is a view in side elevation and partly in section of theumbrella, showing it as detached;

Fig. 2 is an inverted plan view of the umbrella;

Fig. 3 is a perspective View illustrating the um brella as applied to afuel delivery nozzle;

Fig. 4 is a view in section and elevation illustrating the mode ofoperation of the invention;

Fig. 5 is a View in section and elevation depict'- ing a modified formof the invention.

Referring to the drawing more specifically A indicates generally theumbrella, and B designates a nozzle on which the umbrella A is mounted.In the construction shown in Figs. 1, 2 and 3, the

, umbrella embodies an annular resilient collar 2,

on the upper margin of which is formed a flexible which lip convergesinwardly relative :tothe innereperipheryiof the collar 12 whereby.thefouter margin 4of [the lip is iformed vof `an internal diameterslightly less than `that `of the lcollar. v. The collar has aniinternal.diameter slightly lesszthan 5: thejportion of ithe nozzle Bato .beencompassed thereby, aivhereby, in applying `the collarto 4the nozzlathe`collar willlibe'. extended `under :tension in afashionto gripithenozzle. :The .lip'3iwill also be distended'but to a Vgreater .degreethan Vthe `l0 collar so that Vits thin margin will :closely iconfo'rmtothe surface portionlof :theznozzle encircled thereby, ina mannerto'insure againstnthelpassage of'waterbetween the =lip andinozzle. i ,i

Formedfon the collar 12, and projecting .from l5 the underside .thereofisa exible resilient apron Y '5 which flares outwardly xfromithf':fcollariandter.-

minates in an annular margin B of an internal .diameter exceeding theexternal diameter of the rim C of the'ller opening of the fuel reservoir20 of a motor vehicle, so that when the nozzle B- is inserted in suchopening the apron will protrude over the outer margin of the rim of theller opening, as particularly Shown in Fig. 4, in a fashion to prevententrance of water through the 25 opening around the nozzle.

As a means for permitting escape of air displaced during delivery offuel to the reservoir, the inner periphery of the apron is formed with aseries of spaced ribs 1 extending radially from 30 the intersection ofthe apron with the collar to the outer margin of the apron.

In the construction shown in Fig. 5, the umbrella is formed with acircular resilient collar 8 of an internal diameter slightly less thanthat 35 of the portion of the nozzle B to be encircled thereby, and fromthe lower edge of the collar extends a resilient apron 9 which dvergesoutwardly from the collar and is formed on its interior with a pluralityof channels l0 extending radially 40 from the collar to the lower marginof the apron.

The umbrella A may be formed of any suitable material, but theconstruction as illustrated in the drawing is .especially suitable forforming of molded rubber, or rubber composition, and where- 45 by theumbrella A may be readily made in one piece, and as thus formed will beresilient and flexible throughout.

In the application and operation of the invention the umbrella A isapplied to the nozzle B by 50 inserting the nozzle through the upper endof the collar, so that the outer end portion of the nozzle will projectthrough the apron and beyond the lower margin thereof; the collar byreason of being. of lesser internal diameter than the portion 55. Y

of the nozzle encircled thereby being expanded and thereby placed undertension so that when contracted against the nozzle will frictionallygrip the latter under such tension as to securely retain the umbrella inplace on the nozzle.

Where the construction shown in Fig. l is employed, that is with thethin lip 4, in applying the umbrella to the nozzle the lip 4 may berolled outwardly as indicated in dotted lines a in Fig. 1, so as tofacilitate insertion of the discharge end of the nozzle B through thecollar 2, and also facilitate advancing the nozzle longitudinallythrough the collar. After the collar has been disposed at the desiredposition on the nozzle the curled lip may be restored to its extendedposition in which position the lip will be under tension and willtightly grip the nozzle with its thin margin presented upwardly on thenozzle so as to present no obstruction to the flow of water from thesurface of the nozzle above the umbrella onto the outer surface of thelatter.

However in some instances the lip 3 may be dispensed with in which eventthe construction shown in Fig. 5 may be employed in which the collar 8is devoid of an upper marginal lip.

When the umbrella A has been positioned on the nozzle B as illustratedin Fig. 3 the nozzle may be inserted into the filler opening of a fuelreservoir with the apron seating on the rim C of the opening as shown inFig. 4, whereupon any Water flowing down the nozzle B from above theumbrella A will be obstructed and deflected by the latter and will bedirected over the exterior of the apron clear of the intake opening thuspreventing oW of water into the fuel reservoir.

The invention is particularly applicable for use on nozzles of fueldispensing tanks where the hose D leading from a dispensing tank to thenozzle B is exposed to the weather, as is frequently the case in servicestations, since in such locations Water accumulates on the hose during arain and frequently drains therefrom along the nozzle into the fuelreservoir on delivering fuel to the latter. The umbrella A also servesto prevent rain from directly entering the reservoir filler openingwhere the latter is exposed to rain during the lling operation.

By providing the interior of the umbrella with the ribs 1, or channelsI0, spaces are provided through which air displaced by the volume offuel entering the reservoir Will ow through the filler opening and toatmosphere around the lower edge of the umbrella.

While I have shown and described a specific embodiment of my invention Ido not limit myself to the exact details of construction and arrangementshown but may employ such changes in the parts and in their arrangementas occasion may require coming within the meaning and scope of theappended claims.

I claim:

l. An attachment for nozzles comprising a resilient collar formed toencircle a nozzle, a flexible flared apron on one end of said collar,and a flexible converging lip on the other end of said collar.

2. An attachment for nozzles comprising a resilient collar formed toencircle a nozzle, a exible flared apron on one end of said collar, anda flexible converging lip on the other end of said collar, said liptapering to a thin edge to closely conform under tension to the surfaceof a nozzle encircled by said collar.
